SPECIFICATION forming part of Letters Pat-ent No. 363,814, dated May 3ll 1887.

Application filed February 9, 18.87. Serial No. 227,007. (No model.) I

To all whom, it may concern:

Be it known that I, ALPHEUs R. EATON, of Brownfield, in the county of Oxford, Maine, have invented certain new and useful Improvements in Holdbacks; and I do hereby declare the following to bea full, clear, and exact description of the invention, such as will enf able others skilled in the art to which it appertains to make and use the same.

My invention relates to holdbacks for harness; and it consists in the improvements hereinafter fully set forth, whereby a cheap, simple, durable, and effective device is provided that willenable the holdback-strap to upon moving too fast.

. The invention further consists in making the portion which carries the holdback-strap of such shape that it will, whenin position, cover the opening in the shaft in which its stud engages and prevent dust and other foreign matter. from entering said opening, which would prevent the proper working of the device.

In the accompanying drawings, which form a part of this specification, Figure l is a perspective view of a portion of my improved holdback. Fig. 2 is a lcentral longitudinal section of a shaft having my improved holdback applied thereto, and Fig. 3 is a plan view of the plate which is secured upon the shaft.

A refers to a portion of the shaft of a vehicle, which is provided with a recess, a, which is covered by a plate, B, having an opening, I?, formed therein, which opening consists of a circular perforation, which is intersected by a second perforation which is smaller and of elongated shape.

C refers to a spring, which is secured at one end in the front of the shaft-recess, and has its other end located below the elongated opening of the plate. i

D refers to a vertical metallic casting or portion, which is rounded at its front face,

and is provided with a vertical slot, c, for'the engagement of the hcldback-strap'. This said portion D is provided on its under face, at one side of its center,near its front,with a headed stud, d. It will be noted that the lower part ofy the casting D is constituted by a front eX- tending base portion, c, which is preferably of oval form.

In operation the head of the stud d is passed through the larger plateopening into the shaft-recess, and then moved rearward until the said stud is pressed upon by the free end of the spring, which' retains it in position in the recess and prevents its free movement. The neck of the stud occupies the narrow elongated opening of the plate, and the stud is consequently prevented from being vertically withdrawn from the recess. Retained in this position the casting holds the strap vertically, as representedv in Fig. l, and thereby obviates twisting of the same.

The dimension and shape of the casting is such that when the stud is moved beneath the narrow portion of the plate-opening the said plate-opening will be completely covered by the'said base, and the entrance of dirt and other foreign matter prevented.A By this means the shaft-recess is maintained clear 'at all times.

I am aware of the Patent No. 91,831, granted June 291869, to J B. Eaton, for a holdback; and I do not therefore claim, broadly, any feature disclosed in said patent, my present invention bein g in the nature of improvements on said patent.

I claiml. The combination, in a holdback device, of a plate perforated, as described, and a casting consisting of a horizontal base to form a bearing portion upon the upper side of the plate, 'a stud depending from said base to engage said perforation, and a vertical integral portion located on said face and having a vertical slot to receive and hold the strap in a vertical position relative to the shaft, substantially as set forth. x

2. The combination, in a holdback, of a plate having intersecting circular and eX- tended openings, as described, a casting having a horizontal base to form a bearing por- IOO tion upon the upper side of the plate, a the extended opening, substantially as set' headed stud depending from said base to enforth. l ga e said erforations and a vertical inte ral potion ezgtending centrally from saidase ALPHEUS R' EATON' 5 and having a vertical slot to receive and hold Witnesses:

the strap vertically, the relation of the stud F. R. LIBBY, i and base being'such that the latter will cover W. L. GATCHELL.
